BRIEF DESCRIPTION OF DRAWINGS

[0009] Figure 1 is a structural schematic diagram of the utility model. DETAILED DESCRIPTION

[0010] The application will be described in further detail below with reference to the drawings and specific embodiments:

[0011] By Figure 1 It can be seen that the utility model includes: a rotating body connected with the motor of the servo punch; the rotating body includes: a rotating seat 1, a friction block holder 15, a spacer 17 and a friction block group 11; the friction block holder 15 and the spacer 17 are connected to the rotating seat 1 by a screw 16; the friction block group 11 is inlaid in the hole of the friction block holder 15 and can move axially relative to the shaft; further including: a fixed body; the fixed body is connected with the machine body of the servo punch; the fixed body includes: a brake fixing disc 10, a transmission sleeve group 12 and a floating spacer disc 18; the floating spacer disc 18 separates the double-layer friction block group and is sleeved on the transmission sleeve group 12 and can move axially relative to the shaft; further including: an actuating mechanism; the actuating mechanism includes: a cylinder body 2, a piston 3, a first sealing ring 4, a second sealing ring 5, a thrust disc 19, a flange 6, a brake spring 7, a first group of double-headed bolts 9 and a first group of locking nuts 8; the piston 3 is installed in the cylinder body 2 and is sealed by the first sealing ring 4 and the second sealing ring 5; the thrust disc 19 and the flange 6 are connected by the first group of double-headed bolts 9 and the first group of locking nuts 8; the brake spring 7 presses the thrust disc 19 and exerts force on the surface of the friction block group 11 to realize combination; the actuating mechanism is connected with the fixed body by a second group of double-headed bolts 14 and a second group of locking nuts 13.

[0012] The working principle of the utility model is: when the motor shaft of the servo punch operates, the compressed air from outside enters the cylinder body 2 through the air inlet A, drives the piston 3 to act, the piston 3 drives the flange 6 to pull the thrust disc 19 to move to the left by overcoming the brake spring 7, and the friction block group 11 is released. When there is an emergency situation and the servo punch system needs to be braked, the compressed air in the cylinder body 2 is discharged from the A port, the brake spring 7 drives the thrust disc 19 to move to the right, drives the friction block group 11 to be tightly pressed on the brake mounting disc 10, and relies on the friction force generated by the thrust disc 19, the friction block group 11 and the floating spacer disc 18 and the brake fixing disc 10 to realize rapid braking of the servo motor shaft.
